Schedule to run a executable jar file on windows 7 - jar

I created a task in task scheduler on Windows 7 system and made it repeatable every 10 minutes.
In program, i selected the executable java jar file. But it does not run the jar file at the scheduled time.
When i double click and run the jar file, it runs as desired.
The Jar just pops up a dialog box.
Any inputs as to where i am going wrong is appreciated.

Firstly make sure Java is set in the enviroment PATH by opening cmd.exe and typing java -version. If you get back the java version, then you are fine. (If not see Update the PATH Environment Variable (Microsoft Windows))
Then create a text file, save it as run.bat and type inside:
java -jar <insertjavajarnamehere>.jar
Make sure the bat is in the same directory as your jar file.
Now go in Windows Task Scheduler > Create Basic Task > ... >Start a program > and browse for your .bat file.
Also, set Start in to the path where your .bat and .jar are located. Create your task and it should run fine afterwards.
Edit: To avoid the shell being visible a simple trick is to create a VBS file
Create a run-invisible.vbs, and type:
Set objShell = WScript.CreateObject("WScript.Shell")
objShell.Run("C:\Users\pathtobat\run.bat"), 0, True
And schedule that instead of the bat (make sure you update the path to your bat in the vbs file)

A .jar file does not run after building it

Actually, I'm trying to add new language to Streama Media Server. I downloaded source code, added new language file (as guided here). After that, I want to build a jar with that project, I build it with IntelliJ Idea 2021.1 (here is how I did). So, When I run that jar file (in Ubunt 20.04), it fails and gives this error: Screenshot
When you have made adjustments to the source code, it is likely that you will want to create a new .jar file and deploy it on your server. For this, you can use a simple command:
# for unix based systems
**./gradlew assemble**
# for windows
**./gradlew.bat assemble**
This will create 2 new .jar files under build/libs,
streama-{version}.jar
streama-{version}.jar.original
all you will need is the streama-{version}.jar.
This file is an executable, so you can just copy it into your deployment directory / your server and start it as usual.

Get system directory path

I want to upload an image file using an AutoIt script:
WinWaitActive("Open")
Send("D:\sprint8execution\gGastro-mvn\tmp.png")
Send("{ENTER}")
How to give the system-defined path in the script so that if the script runs on any other machine it goes to applicable directory and fetches the image from there?
Have a look to the AutoIt macros. #ScriptDir is the directory that includes the current running script.

Set working directory to mapped network drive in BATCH mode

I'm having issues on windows with R failing when changing the working directory to a mapped network drive (e.g. \Share\Folder mapped to Z:) in batch mode. If I run the same script in an interactive console I don't have any issues. I am accomplishing this by running R.exe with the script specified inside of a windows batch (.bat) file. The .bat file contains the following.
"C:\RRO\R-3.2.1\bin\R.exe" CMD BATCH "C:/Scripts/Rscript.R"
The error is simply...
> setwd( 'Z:/' )
Error in setwd("Z:/") : cannot change working directory
I'd be open to a different approach entirely for scheduling these scripts via the windows task scheduler if that helps avoid the issue. The reason for mapping the drive is that I need to supply some credentials in order to access it, which is done automatically when it is mapped, but can test to see if that's not the case in R if anyone knows how.
I hope this can help with your question.
I duplicated the problem with no errors by using Rscript command instead of a CMD BATCH
my R code which I saved as a script (test1.R)
library(openxlsx)
setwd("P:/Records/Indexing Operations/Indexing Data Analysis/Daily Reports")
my.data = read.xlsx("FSI Daily Project Status Report - 18 Mar 2016.xlsx", sheet = 1)
setwd("C:/Users/golieth/Documents/")
png(filename = "test.png", width = 500, height = 350 )
plot(my.data$Total.Images, my.data$Completed.Images.A,
main = Sys.time())
dev.off()
Note I change the directory 2 times in this file. Once to access data on a mapped network drive and a 2nd to save the image to the computer. I put a timestamp of the current time as the main plot title so you can run the batch file repeatedly and verify it works
my batch file
cd C:\Program Files\R\R-3.2.3\bin\i386
Rscript C:\Users\golieth\Documents\test1.R
Note: On the batch file if your code relies on 32 bit you need to change the directory of your R program (cd) to the R 32bit program. Same with R64. Next the Rscript should reference where you have saved your .R file
Finally, and this might be stating the obvious but make sure you are connected to your VPN before running the batch file.
Imagine a batch file with
cd Z:\<Destination>
Z:
RScript "C:/Scripts/Rscript.R"
This will enable Windows to change to the directory with all credentials and then start R within that directory. So the working dir. is the location from where R is started. Doing so requires that "C:\RRO\R-3.2.1\bin\" is part of your PATH variable.
Good luck!
When writing a .bat file, remember that cd is not used to change drive letters. To change drive letters you simply enter the name of the drive letter, which should be done prior to issuing the final cd to the working directory.
Like this:
sample.bat
z:
cd z:\your\working\directory\
C:\RRO\R-3.2.1\bin\Rscript.exe C:/Scripts/Rscript.R
You can save the files locally in your code, and use file.copy in your code to copy the files over to your network drive. Also try replacing the path in file.copy the network drive letter by the full network address name eg. \\....\.....\

Executable jar file is not responding and not running

I wanted to convert .java file to executable jar file,i did so in the command prompt. But everytime i double click (open) it nothing happens.
jar cf Calculate.jar Calculator.java
This is what i typed in the cmd. How to get an executable file? I use windows
That's not how it works, that way you are creating a jar archive with that .java file in it.
If you want to create the jar manually (if you want to do it one time, instead of using a build tool like ant or maven, it could have some educational value), you have to compile your .java file to a .class with javac, add it to the jar and then modify the META-INF/MANIFEST.MF manifest file to specify Calculator as value for the Main-Class attribute.
See this old guide from Sun.

jar file not found iexpress

I am using iexpress to make my .jar files into .exe files
for this I add the jar file(myjarfile.jar) and in run command box I type : java -jar myjarfile.jar
but after creating the .exe the cmd that is flashing says cannot find the jar file myjarfile.jar
can any body help me find what I am doing wrong
To test this, I built a simple HelloWorld.jar file (using these instructions) and tested it like so:
java -jar HelloWorld.jar
Then I made an IExpress package with it. The Install program was exactly the command I used above. This worked exactly as it should.
Two possible causes of the error:
In the IExpress wizard, there's a checkbox Store files using Long File Name inside Package. You should definitely select this option; ignore the warning that appears, as it applies to Windows 95/98. In the .sed file, this is:
UseLongFileName=1
Check that the .exe actually contains myjarfile.jar. 7-Zip will open the .exe and show you the archive contents. (IExpress .exe files are just a CAB file with a wrapper.) If the file is missing, then you'll need to check your .sed file to see what went wrong.
